Subsequent Events [Abstract]
Subsequent Events	Subsequent Events We have evaluated subsequent events from the balance sheet date through March 20, 2020, the date at which the consolidated financial statements were available to be issued. Subsequent to January 31, 2020, we entered into an agreement to lease additional space and extend the term of existing leases located in the United States. We expect to make $8.9 million of additional rent payments over the term of these leases, which expires during the year ending January 31, 2030.
